a control helps to increase the reliability of the results. it allows a scientist to compare it to other group(s) in an experiment. if a scientist notices a significant different btwn the control and the other groups, he can logically conclude that the independent variable has an impact on the dependent variable.
a variable is any factor, trait or condition that can exist in differing amounts or types. there are usually three tpes of variables in experiments: the independent, dependent and contolled. the independent variable variable is the one that is changed by the scientists to figure it's affect on something.
Well bears hibernate and the fat source plays a major role in giving them the energy they need to survive while hibernating.
In general cells that need more energy, since mithocondria are responsible for making and processing ATP.
Common examples of cells with many mithocondria are muscle cells that are in current activity all the time, specially heart muscles and muslces in the respiratory system such as the diafragma since the heart beats all the time, non-stop, that is, unless you die of course and so do the muslces needed to breath.

Answer:
Option C. Cellular transport that does not require cellular energy, is the correct statement.
Explanation:
Movement of molecules requires energy for transportation from one place to another.
Passive transport is a type of transport in which molecules moves from one place to another without the use of energy. In passive transport, one molecule pulls another molecule and as a result the molecule moves from one region to another.
